Specification of Letters Patent.

Patented March 2, 1909.

Application filed September 17, 1907. Serial N o. 393,372.

To all 'whom 'it may concern.'

Be it known that I, REN FRANooIs CHARLES RAMBEAUD, a citizen of theFrench Republic, and resident of Parthenay, Deux- Svres, France, haveinvented a certain new and useful Beating and Kneading Machine, of whichthe following is a specification.

The object of the invention is to provide a novel machine for beatingthe glair of eggs, for beating biscuits, mayonnaise, and the like, andfor kneading soft or hard pastes by means of interchangeable beating andmalaxing members, which machine shall be simple of construction,thoroughly efficient in operation, and durable in use.

In the annexed drawing given by way of example: Figure 1 is a sideelevation view of the above machine arranged for one application. Fig. 2is a front elevation view. Fig. 3 is a detail view partly in section,partly in elevation of same. Fig. 4 is a side elevation view of themachine arranged for a second a plication. Fig. 5 is a front elevationview of) the beating member adapted to serve for this application. Fig.6 is a detail view of a whip carrier. Fig. 7 is a detail view of abeater. Fig. 8 is a detail view of a different form of beater. Fig. 9represents a beating member adapted to be used in connection Withanother ap lication of the machine. Fig. 10 is a detaiFview of amodification of certain parts shown in Figs. 1 and 2. Fig. 11 is adetail view of a modification of certain parts shown in Fig. 9.

The machine shown in Figs. 1 to 3 comprises a framework l upon which ismounted a shaft carrying a large toothed wheel 2 and a driving fly-wheel45 the said toothed Wheel driving a small spur pinion 3 which by meansof a flexible shaft 4 transmits a rapid rotary i motion to a small bevelpinion 5 mounted on the movable arm 6 of the bracket 7 secured by twotightening struts and by a nut 82 to a ring 27. This small pinion 5drives the bevel 8 which is movable on the shaft 9 (Fi 3) secured to thehead of the arm of the racket 6 by means of the nut 10 which also allowsof the ball bearing 11. The suspension member l2 having the form of astirrup carries by means of the two trunnions 13 a ring 14 which isitself provided with two poles 15 perpendicularly arranged to the axisof the trunnions and wherein a pin is engaged which crosses the upperend of the shaft 16 of the beating member which has any desired form.The arm 6 may be fixed at the desired height on the standard 7 by meansof a pressure screw 42.

The shaft of the beating member or beater passes through the ring 17 ofthe great lever arm 18 the axis 19 of which is made integral with thebevel wheel 8. A spring 2l has a tendency to move away from the centerthe long arm 18 which is then adapted to apply the beater 16 upon thewall of the basin 22 while the small arm 20 of the said lever whichpasses through the wheel 8 abuts against an eccentric 23 (Fig. 3) madeintegral with a toothed wheel 24 which is mounted upon the bevel wheel 8and meshes with a small spur pinion 25 which is itself made integralwith the shaft 9.

The ring 27 mounted on the shaft 29 is adapted to take dierentinclinations during the operation ofthe machine by means of the toothedsector 30 driven by the worm 3l and by the small crank 32. Upon the saidring 27 is secured the standard 7 carrying the above cited beatingsystem and which follows the inclination of the said ring. On the saidring also reposes by the intermediary of a ball bearing system, a secondtoothed rinol 28 which may have the form of a bevel Whee 28 (see Fig.10) and in this case is rotated by a conical pinion 33 (Fig. 10). Thering 28 (Figs. 1 and 2) may also have a helicoidal toothing 28 and beactuated by a worm 33 driven by a flexible shaft 37 (F i0'. 1). Thissecond ring is held on the ring 27 by means of the small rollers 34 thepressure of which is controlled by means of the screws 35. This ring 28receives the basin 22 containing the products to be beaten and carriesit on With it in its rotary motion transmitted thereto by the worm 33,the flexible shaft 37 and the small pinion 38 mounted upon a movablemember 39 held in mesh with the big toothed wheel 2 by the spring 40secured to the arm 4l of the framework 1; it is consequently possible toremove the pinion 38 from the wheel 2 in order to render the ring 28 andthe basin stationary.

Secured to the standard 7 is a stud 36 upon which is adapted teoscillate an arm 84 carrying a Scraper 43 which may be a plied by aspring 85 against the inner wa l of the basin 22.

This a paratus works as follows: Movement of t 1e ily-wheel 45 rotatesthe wheel 2 and, through the intermediate mechanism, causes the beaterto travel around the interior sides of the basin. The eccentric 23, in-

tegral with the wheel 24, intermittingly engages the lever-arm 20, whichrocks the beater-arm i8 with the beater toward the center of the basin.As soon as the eccentric leaves the arm 20, the spring 19 returns thelever to normal position. la this manner, the beater reaches all partsof the basin, in the similitude of hand-beating, and b r niy peculiarmechanism the high speeds used in other beaters may be dispensed withand better product obtained. The scraper 43 acts, with gentle pressure,upon the inner walls of the basin, to return trie preparation to thecenter thereof, rendering the beating operation perfect.

It may be advantageous especially for genoeses and biscuits to raise thepaste in order to aerate it and to render it lighter. Vilith a view ofsecuring this result the pressure screw 42 which secures the arm 6 tothe standard 7 (Fig. i) is loosened, the flexible shaft 4 is separatedfrom the pinion 5 in order to remove the beating device: then the nuts82 are unscrewed thus allowing of the standard 7 being shifted andsecured on the studs 44 in a position wherein it is perpendicular vidthreference `to its iirst position. Thus the standard instead of occupyingthe position shown by Fig. 2 may be placed in the inclined position,shown by Fig. 4 when the whole ring carrying the basin oscillates aroundits axis 29. Then the sleeve 45 is slid on the rod of the said standardand secured thereto by means of the screw 47, this sleeve carrying thebeating device adapted to oscillate around the trunnion 46. This beatingdevice comprises a member 48 having a suitable form and hollowed outpart A according to the dotted lines shown in the drawings, so as toform two cheeks surrounding the sleeve 45. One (50) of these cheeks hasan opening 5i through which passes the screw 52 which is adapted tosecure the device in the chosen position. The said member 48 carries twotoothed wheels 53 having the same diameter and the saine number ofteeth, these toothed wheels being rotated in the same direction by thepinion 54 mounted upon the member 48 connected with the flexible shaft4. The two wheels 53 are provided with two radial openings 55 in which.

.are adapted to slide the sliding members 56 which may thus be placednearer the center of the said wheels 53 or farther away from thesecenters, The trunnions of these sliding members 56 are connected by therod 7 O upon which slides the member 57 which is secured by means of thenut 58 at the desired height. The member 57 carries at its end the whipcarrier. The latter comprises a stud 62 (Fig. 5) made integral with ahalf collar 63 connected by a hinge 67 with another half collar 63 thesetwo half collarsfbeing adapted to be held against one another b y aspring member 64 and then form a chamber (Figs. 5 and 6) in which ayielding ring 65 is inclosed; through this i'ing passes the shaft 69 thebeater of which is provided with an annular groove 68 adapted to beengaged by the two halves of the ring 66 which holds the whole laterallywhile affording a certain suppleness. The whole is connected with themember 57 by means of a lug 62 having the form of a quadrant and by apivot 66 so that the beater may receive any desired inclination in whichit is held by the tightening screw. This form of execution worlrs in thefollowing manner. The whole having been put in place, the screw 52 (Fig.5) is loosened. Then by means of the worin 3i and of its toothed segment36 (Fig. 3) the whole basin carrier 27 is inclined; the standard 7 thenassumes the position shown by 4; the member 4S which is freely suspendedby the trunnions 46 assumes a vertical position; then the nut 52 istightened in order to secure the memb r 48 in position; then theingredients necessary to the manufacture of the paste to be produced arepoured into the vzifasin, beginning with the eggs or other liquid, themachine is then started whereby the fiexible shaft 4 rotates the pinion54 which actuates the two wheels 53 the rod 70 thus performs a verticaland circular motion; the beater 69 raises the paste and causes it tofall again thus introducing therein a great amount of air which rendersit frothy and light, giving a much greater output with a much lesserspeed. The inclination of the machine may be varied during theworlrwhich is a great boon.

N hen a soft paste is to be produced such as a paste for iight cakes, orfor savarin, the member 57 is removed and replaced by the member 7i(Fig. 8) having a suitable sha e, the inclination of the basin beingmodi'ed in such a manner that the rod descends in its center and 'withit the member 7 l which has about the forni of the recipient. Thisapparatus worlis in the foilowing manner: During the work, the basin,while rotating slowly brings the paste under the member 7 l which duringits vertical and circular motion raises it and causes it to fall againjust lil-:e the hand of the baker. The amplitude of the motion of therod 79 is varied by shifting forward or backwards the slide members 56in their grooves and Afixing them by means of the nuts 7 2 (Fig.

ifhen firm pastes to be worked the arm or bracket of the sta-.ir-.ard isreplaced by that 73 sli wn by Fig. 9. This arm has a suitable forni andcarries a malaxating device composed either of a bevel wheel when themotion is transmitted -by a bevel pinion (Fig. 1l) or of a helicoidalwheel 74 when the transmission taires place by moans of a worm 75. On"l" this wheel 74 are arranged two vertical sha'lts 7S provided withspirally arranged wings 80. Secured to these shafts are tWo smallpinions 76 adapted to receive motion from a third toothed wheel 79secured to shaft 77 which is tightly secured to the top of the arm 73 bymeans of the nut 81. For using the device the small pinion 3S (Fig. 2)is removed from the toothed Wheel 2, if it is desired to render thebasin stationary. The latter is then placed into the horizontal position(Fig. 1) 22 the malaxator is then lowered into the basin or into a dishhaving a flat bottom; the liquid materials necessary for the preparationare then poured into the dish and afterward the other materials such asflour, butter and so on the machine is set going and by means of' itsflexible shaft the latter causes the Wheel 74 (Fig. 9) to rotate throughthe intermediary of the Worm 75; the shafts 78 which are carried by thesaid toothed Wheel performa satellite motion around the shaft 77 owingto their pinions turning around the fixed pinion 79 and the Wings 80 miXin a perfect manner the ingredients placed into the dish or basin.

The device shown by the Fig. 11 comprises a standard arm 89 having asuitable form and upon which is a screw S2 provided with a shoulder andada ted to serve as a shaft for the angle Whee 83 made integral with asmall spur inion 85 meshing with two small spur Whee s 86 and 86 securedto the shafts 87 of the malaXators provided with helicoidal Wings. Thesmall bevel pinion 88 receiving its motion from the flexible shaft 4transmits it to the bevel Wheel 83 which carries on the other members ofthe device mixing thus in a most perfect manner the various ingredientsdisposed in the recipient.
